What you are proposing, are basically "all should buy DJI stuff" - no DIY solutions (who will spend $$$ on their custom FC certifications? So far hundreds of custom - not derived - FC designs exist), no INS development (as you need coords, bye Paparazzi and other OSS projects with innovation), no drone racing (nobody uses GPS on them), no micro-indoor (again no GPS on them), no custom video-data-transfer solutions (bye, wifibroadcast, fpv-blue, etc...), <....>
In other words - "only DJI stuff should be allowed in shops, everything else should be banned, including information how-to-DIY or development". Working for chinese company, eh?
BTW, you do not need aeroscopes or multi-million stuff for tracking copter, which is transmitting something (telemetry, video stream, <....>) - AD8318 (entire board with connectors and stuff ~20$ on ali), teensy (as ADC) (10$), OLED screen (2$) and wideband directional antenna (DIY in 20min) - done, you can track any copter in air without visibility, in few km range (depends on transmitting power) and do not require any propieritary DJI solutions. Done that few years ago - so why add requirement for aeroscope?
But if you want to be really stealth and resistant - go with INS instead of GPS (OSS solutions aren't so precise, but works), disable all telemetry/control/video stuff, just waypoints - done. Jammers won't do anything to you (unless they are super-powerfull so disrupt sensor work), you also won't be traceable using common tools. Only radar and eyes will work as detection tools and direct hit will be required to crash it (bullet, laser, whatever). I guess, this was done on airport, because all common tools proved to be useless....
